.igure I'is a side-elevetonofija m or `l5 scribed and inthe present i-nstenoe the body A 23 is'shown 'as of the box type having i. hase freine-Work 24:, cross members 25 and suiteble 4side-1 panels 2 6., The hase 2 4 is pivotel'ly mounted upon ,theframel :it 27' by a this latter mechanism being shownlparticularly in Fig. 4. One end of the ,shaft extends to a position adjacent '.thc-i'driving shaft 16 of the motor and is at right angles thereto. lt is provided with a bevel gear 36 which is arranged within the housin' 16 hereinabove referred to, and the gear i156' in constant mesh with a pair of opposed bevel pinions 57 and SSgvhiob are arranged loosely upon thc shaft 16, this latn ter arrangement being' best shown inFlg. 3. '.lfhefshaft 16 in. fact has itsuwholi-z" bearing in the casing 18 through these pinions 3 and 38, the latter being mounted in bearings 39 and 40 res iectively in said casing 18,

Also mounted upon 'the section of the shaft 16, which extends through the casing 18, is a double clutch member 41 which is keyed to the shaft 16 as by a key 42 and which providedwith clutch teeth 43and 44 on its respective ends. The member 41 is adapted to be moved longitudinally on the sha'lft 16 to positions .in contact with either pinion or the pinion 36. The pinion. 3'? formed with clutch teeth 45 which co operate vwith the clutch teeth 43, and the pinion 38 is formed with clutch teeth 46 which coperate with the clutch teeth 44.

A rocking yoke. 47 is pivotally mounted within the casing 18, as at 46, and is provided with lingers 49 which operate in an annular groove 50- in the member 41, thus providing means for moving the member 41 while the shaft 16 is in motion, so that it may be in clutching engagement with either the. pinion 37 or the pinion 86. Abell crank lever 51 is secured, upon the pivot pin 48 on the outside of: the casin 18 and is adapted to becoiitrollcd by the operator through a rod 52 and a hand control lever 53 to which the rod connected. This lever 53 is f d conveniently to the operators seat ls through a plante 54 in a slot 'l'he slot 55 i two parts, as '.'icularlyin Figs. g5 and 6, and the p t; are odset from each other so that the lever 53 may be moved into one extrem ity of the slot, as shown in Fig. 6, and-in oi lcv move it to the other extremity of ythe :slot-it must berocked laterally at the center of the slot. As the center ofthe slot he neutral position of the lever, it will En that when the lever is in one of' the fne positions it will` strike against the the offset portion of the slot if it is suddenly' moved toward the other extreme positirm.. Thus the operator is prevented from going quicltlj from one eXtreme position to the oth 1r. so that the rotating parts will have a better opportunity to come to rest and. the machinery sub'jectedto less jar than if. the opera-tor were free to move the lever `53 (prickly from forward position to reverse, or vice versa. 1

A controlrod- 56 is suitably supportedby the housing 29 and arranged' longitudinally thereof in a position adjacent the forward end of the body 28 and is connected to one of the arms of the bell crank lever 51, as at 57. The rod 56 is provided with stops 58 and 59 adjacent its. respective ends, and a part. 60 of the forward end of the body 23 is adapted to travel adjacent the rod 56 as "the body is moved to dumping and nonrfiuinping positions and to contact With the stops 58. and 59 respectively and thereby move the rod 56 with the body toward the end of its normal travel. As shown, spring buffers 61 and 62 are'used to ive a quick movement to the rod 56. It will be seen that as the spring device 62 comes in contact with the stop 59 the spring will be compressed .somewhat before the rod 56 will be moved with the body, by reason of the friction that must be overcome, but when the rod does start to move, the spring will tend to accelerate its movement, and the bell crank lever 51 will consequently be rocked quickly and the clutch member 41 will be quickly withdrawn from its clutching engagement with one of the pinions 37 or 38. In this movenient, the lever 53 will also be moved lfrom the extreme position in which it was vplaced by the operator and it will strike against;

the wall of the offset portion of the slot 55 and thereby stop the further movement of the member 41. The lever 53 may then be locked in its central or neutral position, as shown in 55, by a latch 63 which is hinged, as at 64, to the plate 54. The lateh'is shown in its locking position in Fig. 5 Aand in its unlocked position in Fig. 6.

spring 65 is shownin Figs. 1, 2 and 3 as connecte/d to the pivot 57 and one of the cross traine members 19. This spring is adapted to maintain the clutching member 41 yieldigngly 1n clutching engagement with either of the pinions 37 or 38 andit is shown as being slightly above the line of the pivot pin 48 so that it will act to balance to some extent the weight of the rod 56. Were -it not for this balancing eifect, the weightof I" the rod 56 would always tend to throw the clutching member 41 into engagement with the pinion 37.

A bracket 66 is preferably secured to the may also be strengthened or braced. as by longitudinal brace rods' 68.

It, will be understood thatthe motor is` ing mechanism, or with the dumping mechanism, hereinabove described.

The operation of the mechnniem may be descril'lcd :is follows:

AvVitli the parts in the posit-ion shown in Fig.V l., that is, with the body at rest in its normal or non-dumping position, :1nd the motor running idle, the motor clutch is dis engnged by the operator, which permits the seqnently the bevel gear 36. Thence through the intermediate slm fr 35, the Sprocket geen "ing 554, the ehnft i sind the gearing 3ft the eci-ew or warm :il i5 rotated and the bloei; 2l in rained and with; it the front 0nd of 25 the body.
